"Funny" how the most elementary aspects of personal mobility are left out. Then again, not surprising coming from an OEM that wants to sell us much rolling hardware as possible. Look, if we want to talk 'fundamentals', let's address some basic facts then.

1. Average car occupancy is 1.2 person and is especially low when roads are filled with commuter traffic.

2. Car is wider than that single occupant is tall; this comes down to expecting to make progress whilst a person is lying sideways across a lane.

3. Average car weighs 20-30 times the usually single occupant (the driver). Batteries only add to the weight.

4. The electric car is to become a household's biggest appliance - the bigger the more batteries and demand from the grid needed.

1-2-3-4 explains the extreme wastefulness in personal mobility when it comes to using energy, materials, road space and... time.
